Specification of Letters Patent:

Patented Aug. 21, 1906.

Application filed December 4. 1905. Serial No. 290,236.

To all whom it may corwern:

Be it known that I, WALTER L. LINDBLOM, a citizen of the United States, residing at Me- Cracken, in the county ofRush, State of Kansas, have invented certain new and useful Improvements in Spindle-Bearings, and I do hereby declare the followin to be a full, clear, and exact description the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bearings, and more particularly to those for cultivatordisks, and has for its object to provide a bearing which will be practically dust-proof and which will be simple in arrangement and construction.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the present disk-bearing. Fig. 2 is an edge view of the disk. Fig. 3 is a central longitudinal section of the bearing on line 3 3 of Fig. 1. Fig. 4 is a cross-section on line 4 4 of Fig. 2, part of the flange, with a cap, being broken away to show the oil-feed screw. Fig. 5 is a detail sectional view of the oiling-plug.

Referring now to the drawings, there is shown the usual supporting-shoe 5 for a disk 6. In the shoe there is secured a laterally-e tending stub-shaft 7, which is surrounded by a circular recess 8, formed in the shoe, as shown. The disk 6 has a central 0 ening 6, in which the stub-shaft is engage for rotation of the disk thereupon, and a collar 9 is revolubly engaged with the shaft within the recess 8 and has a flange 9, to which the disk is secured, the flange resting against the inner face of the disk, which is that face lying adjacent to the shoe. An outwardly-tapered spindle 10 is formed integral with the stubshaft at the opposite side of the disk from the shoe, and at its inner end this spindle is provided with a circular flange 11, against which the disk rests. A plurality of bolts 12 are passed through the flange 9 and the disk and surround the flange 11., these bolts holding the flange 9 to the disk.

A tapered boxing 13 is engaged revolubly upon the spindle l0 and has a laterally-extending flange 13 at its major and inner ends, this flange 13 resting upon the flange l1 and having an annular flange 14 at its outer periphery which extends toward the disk and incloses the flange 11, and this flange 14 has openings 15 formed therethrough which re ceive the bolts 12. Longitudinal slots 16 are formed in the boxing, and in the outer face of the flange 13 there is formed a radial transversely-concaved recess 17, which opens through the outer periphery of the flange at one end and which communicates at its inner end with a larger recess 18, formed in the flange and extending to the boxing. The re cess 17 has half-threads formed therein, as shown.

A nut 20 is engaged with the stub-shaft 7 outwardly of the boxin r, and engaged over the boxing and the nut ti ere is a solid cap 19, having a circular flange 21. at its inner end, which rests against the flange l3 and which receives therethrough the bolts 12, nuts being engaged with the bolt outwardly of the flange 21 to hold the several parts in position.

A recess 22 is formed in the inner surface of the flange 21, coinciding and registering with the recess 17 and having half-threads to form with the recess 17 a threaded passage, and a recess 23, corresponding to the recess 18, is formed in the inner surface of the flange 21, communicating with. the recess 22 and with the interior of the cap 19 and registering with the recess 18 to form an oil-chamber, and this oil-chamber and the threaded passage lie between the flanges 13 and 21, as will be seen. An oil-feed screw 24- is engaged in the threaded passage and has an annular enlargement 25 at its inner end, which lies within the oil-chamber formed by the recesses 18 and 22. A longitudinal duct 26 is formed within the screw 24, opening through the inner end of the latter, and at its outer end the duct 26 opens through one side of the threaded portion of the screw, as shown. The arrangement is such that the screw may be screwed into the passage to bring the laterally-turned portions of the duct into the passage to prevent ingress of dust to the duct, and the screw may be unscrewed to permit of the introduction of oil through the laterallyturned end of its duct. The bolts 12 maybe loosened or tightened to vary the adjustment of the bearings, as will be readily understood. The spindle 10 has an inward extension (1, which is cylindrical in form and which is concentric with the stub-shaft and lies within the opening 6' of the disk 6 and within the collar 9, the collar and disk thus revolving upon the spindle, which is hardened to minimize the wear.

What is claimed is 1. In a disk-bearing, the combination. with a support having a recess therein, of a stubshaft engaged in the support and extending outwardly through the recess, a collar revolubly engaged with the stub-shaft within the recess, a disk revolubly engaged with the shaft at the outer side of the collar, said collar having a flange resting against the disk, bolts engaged in the flange and disk, a spindle carried by the shaft outwardly of the disk and having a flange at its inner end lying within the inclosure of the bolts, a longitudinally slotted boxing revolubly engaged with the spindle and having a flange at its inner end, said flange having an inwardly-extending annular flange at its outer edge surrounding the flange of the spindle, said annular flange having openings in which the bolts are engaged, a cap engaged with the boxing and having a flange resting against the first-mentioned flange of the boxing, said bolts being passed through the flange of the cap, retaining devices engaged with the bolts outwardly of the capflange, said first-mentioned flange of the boxing and the cap-flange having an oilchamber formed therebetween and having a threaded passage formed therehetween and communicating with the oilchamber and opening through the outer peripheries of the flanges, and a screw engaged in the threaded passage, said screw having an enlarged inner end lying within the oil-chamber and having a duet opening through its inner end and through one of its sides, said screw being oper- 1 able within the threaded passage to bring the opening in its side into and out of the passage.

a support, of a stub-shaft carried by the support, a disk revolubly mounted upon the stub-shaft, a spindle carried by the shaft outwardly of the disk and having a lateral flange at its inner end, a boxing revolubly engaged with the spindle and having flanges extending over the outer and peripheral faces of the spindle-flange, a cap engaged over the boxing and having a flange, bolts engaged in the disk, the flanges of the boxing and the flange of the cap, said boxing having longitudinal slots therein, and means for admitting oil to the space between the boxing and the cap.

3. In a diskbearing, the combination with a support, of a stub-shat t carried by the support, a spindle carried by the stub-shaft and having an ani'iular flange between its ends, a disk revolubly engaged with the spindle between the flange and the support, a collar revolubly engaged with the )indle between the disk and the support and having a flange resting against the disk, a boxing engaged with the spindle outwardly of its flange. and having flanges surroul'iding that of the spindle, a cap engaged with. the boxing and having a flange resting upon one of the flanges thereof, fastenil'ig devices engaged in the flanges of the collar, the boxing and the cap and in the disk, a nut engaged with the stubshaft outwardly of the boxing and within the cap, and means for introducing oil between the cap and boxing, said boxing having oilpassages therethrough leading to the spindle.

In testimony whereof I aflix my signature in presence of two witnesses.
